When I Walked In on Her, I Couldn't Turn Away

I'll never forget the day I walked in on my stepsister, Sarah. It was a weekend afternoon, and I had just gotten back from my friend's place. Unlocking the front door, I called out her name, as was my habit. No answer. The house felt unnaturally quiet. Stepping further inside, I noticed her bedroom door was ajar. Curiosity piqued, I crept closer and peered in.

What I saw took my breath away. There was Sarah, my hot stepsister, standing in the middle of her room, dressed—or rather, undressed—in a way I had only seen in my wildest fantasies. She wore a black lace bra that pushed up her already ample cleavage and matching panties that disappeared into her thighs. But that wasn't the most shocking part. Sarah had her back turned to me, and as I took a step inside, I noticed something I had never seen before. Her hands were bound above her head with a dark red scarf, and a blindfold covered her eyes. She was completely at my mercy, and I felt an exciting jolt of power course through me.

She must have heard me come in because she stood still as a statue, her breath quickening. I closed the door quietly, not wanting to interrupt whatever game she was playing. My heart pounded in my chest as I approached her, enjoying the shy, embarrassed smile on her face. With each step, the swish of my pants seemed to echo in the silent room, the tension growing with each moment.

I cleared my throat, unable to think of anything clever to say. Sarah's eyes widened behind the blindfold, and she took a step towards me, her chest heaving. I couldn't help but notice the way her nipples strained against the fabric of her bra, and a trail of moisture seemed to glisten between her thighs. I was transfixed, and my own pants grew tight.

"W-what are you doing here?" she asked, her voice a mix of embarrassment and excitement.

"I live here, remember?" I teased, enjoying her flustered state. "But it seems like you're up to something fun."

Sarah's face flushed a deep red, and she lowered her head. "I-I'm not sure. This is kind of new to me. I'm just testing it out."

"Well, it looks like you're having a good time," I said, stepping closer and running a finger along the edge of her bra. "Mind if I have a better look?"

She bit her lip, a silent plea for me to continue, and I felt a thrill run through me at her submission. Slowly, I circled around her, taking in the sight of her bound hands and the way her body reacted to my every move. I stopped behind her and traced a finger down her spine, enjoying the shiver that ran through her body.

"You're so beautiful, Sarah. And brave, too," I whispered in her ear, leaning in close so that my breath tickled her neck.

She shuddered, and I could feel the heat of her skin against my face. Impulsively, I left a trail of licks and hickeys down her neck, enjoying her sharp intake of breath. Then, I unhooked her bra, freeing her tits from their lace confinement. They fell heavy and full, and I couldn't resist running my hands over her soft skin, thumbing her stiff nipples.

Sarah sighed and pressed back against me, her bound hands straining against the scarf. I dipped my head and took one nipple into my mouth, savoring her taste and the way she moaned in response. The other breast received the same treatment, and I watched with delight as her hips began to move, her breath coming in gasps.

Knowing she was ready for more, I kneeled before her and turned her face towards me with a gentle hand.

"I've wanted to do this for so long," I confessed, my voice rough with desire as I unbuckled my belt.

With expert fingers, I unfastened the blindfold, and it fell away to reveal her deep blue eyes, glazed over with lust. I lowered my head and licked her lips, tasting her sweetness as her eyes drifted closed. I ran my tongue along the seam of her panties, savoring her flavor, before slipping them off her hips.

Now fully naked, Sarah's inhibitions seemed to melt away. She thrust her hips forward, silently urging me on. I obliged her, diving into the moist folds of her pussy, and felt the wetness on my lips. Her flavor was intoxicating, and I devoured her, using my tongue to tease her clit and probe her entrance.

Sarah's hands gripped my head, and she moaned loudly, her body quivering. I looked up at her, enjoying the sight of her bound, helpless form as she writhed before me.

"Oh God, please don't stop," she begged.

I smiled against her heat and resumed my task, determined to make her beg for release. Her flavors surrounded me, and I lost myself in the moment, licking and sucking until Sarah's hips bucked wildly, and she came with a loud cry.

When she finally came down from her peak, I stood up and stripped off my clothes, my erection straining before me. Sarah's eyes widened at the sight, and she licked her lips, her hands still bound above her head. I took hold of my cock and stroked it, using my other hand to guide it to her waiting mouth.

She took me in eagerly, her eyes never leaving mine as she sucked and licked, her skilled tongue driving me wild. I could feel the buildup of tension in my loins, and I knew I wouldn't last long.

"I'm gonna cum, Sarah," I warned her, and she looked up at me with a smile that said she was ready.

I thrust my hips forward, and she took me deeper into her mouth. The sensation was too much, and I released myself, my cum shooting into her waiting throat. She swallowed every drop, milking me with her mouth until I was spent.

As I came down from my high, I untied the scarf from her hands, enjoying the way she rubbed her wrists as circulation returned.

"That was better than I even imagined," I breathed, leaning in for a deep kiss.

Sarah sighed, her hands now freely running through my hair. "You caught me practicing for a date... I guess you could say you saved me from a very frustrating evening."

I grinned, feeling more connected to her than ever before. "Well, consider me your personal savior then. And if you ever need another saving, you know where to find me."

She laughed, and we lay down together, our bodies still humming with satisfaction. And I was already eagerly awaiting our next encounter.
